This month’s Facility File focuses on the March Back2Basics retrofit of a campus-wide hot water boiler system covering 40 buildings with primary-, secondary-, and tertiary-pumping based on a performance lease agreement to retro-commission the system with a guaranteed operating savings. The university will hire an owner representative to work with a design-build-operate-maintain performance contractor (PC).
According to Greenheck, its new Model AER direct drive sidewall propeller fan moves 30% more air compared to similar fans. This allows for a smaller fan size to be specified in order to achieve desired performance while reducing first cost.
Johnson Controls introduces Metasys® Enterprise Management, a cloud-based optimization platform that analyzes building energy and equipment data across an enterprise to identify issues and opportunities for performance and operational savings.
Greenheck’s new Model EQD direct drive mixed flow inline fan features an energy-saving Vari-Green® motor mounted inside a patent pending octagonal housing. The company says the Vari-Green motor’s variable speed control matches fan performance with facility demand and requires virtually no maintenance.
Bell & Gossett introduced the new ecocirc® 19-16, a variable speed ECM circulator with onboard intelligence that automatically adjusts pump performance to ensure the highest efficiency over a wide operating range.
The EME520V wind-driven rain-resistant stationary louver is the newest louver offering from Ruskin®. The company says this 5-in vertically-oriented louver has best-in-class wind-driven rain performance (Class A at 29 and 50 mph) along with good pressure drop. The EME520V is constructed of extruded aluminum for low maintenance and high resistance to corrosion, and is AMCA certified for both wind-driven rain protection and air performance.
Taco Comfort Solutions has added new features and capabilities to its large 00e VR ECM, wet rotor commercial circulator line designed for chilled and hot water applications. Available in four sizes (VR 15-3, 20-3, 25-3, and 30-3), the sensorless 00e VR line provides differential head pressures up to 42 ft and flows up to 360 GPM.
Trane is expanding its portfolio of Performance Climate Changer™ air handlers to provide customers with a custom unit that is designed and built for applications that require exact specifications for size, shape, components, materials and performance.
On Demand Maintaining a single point of control for a building’s mechanical systems through integration makes facility management easier and more effective. With HVAC systems responsible for a significant part of a building’s energy costs, this webinar explores the range of integration options available to owners and managers interested in maximizing efficiency and access to information across mechanical systems as they achieve optimal performance of VRF, a sophisticated HVAC technology.
Engineered Systems magazine’s March 2019 issue examines the innovations offered by manufacturers at the 2019 AHR Expo and engineers at the ASHRAE Winter Conference, explores the difference between direct drive and belt drive fans in institutional applications, compares and contrasts the prescriptive and performance paths for boiler compliance, and much more.
